JLospinoso/gargoyle ? reverse-engineered prompt

Build me a Windows research demo that shows how a benign action can be observed during a short active window, then the relevant code stays non executable while it waits and comes back later through a timer and alertable sleep callback.

I want the original Win32 x86 version to be the main reference, with sibling demos for x64, ARM64, and ARM64EC, plus clear docs that explain what each one does and what it does not prove. Please include a simple validation flow I can run locally, with a couple of visible tests that show initial execution and later re entry, and keep the language careful since this is for research, not for stealth or misuse.

If you need to, look up current docs for the build tools and any Windows behavior details, but keep the project self contained and easy to follow.
